Abstract

The method involves directing a cutting beam (5) at the workpiece (1) that penetrates the workpiece under control dependent on a detected parameter reproducing the state of penetration of the workpiece. At least two potential control parameters are continuously detected before penetration through the workpiece, at least one potential control signal is produced per parameter and assessed against usability criteria. Independent claims are also included for the following: an arrangement for flame cutting of workpieces.
